Austin Ekeler’s 6.9 Yards per Touch and +54.5 Production Premium were both No. 1 among qualified RBs in 2019. That kind of efficiency doesn’t repeat itself, especially when a team is breaking in a new QB and new Left Tackle in the wake of Russell Okung’s departure. With such significant offseason turnover and expected efficiency regression, be cautious of projecting similar production for the Chargers this year.

How likely is it that Raheem Mostert, a 28-year old, former undrafted free agent with a 25.9 (0th-percentile) BMI, matches last year’s fantasy success? If the defense and the running game regress in San Francisco, that will mean more passing opportunities. This confluence of factors makes the team a risky bet to invest in for fantasy this year, particularly in the run game.
